When shopping for the quietest water flosser, full-size models are out of the question. Through our research and own experience, we’ve learned that all full-size models feature loud motors. Fortunately, there are cordless and portable units that fit the bill. More and more people are switching to cordless for the sake of convenience and portability.

In this guide, we share the top 5 quietest water flosser models currently on the market. In addition to sharing the specs of each unit, we share our reviews and the pros & cons. Over the years, we’ve become quite good at sniffing out reasons to and not to buy a product.

If you’re anything like me, loud sounds disturb you, and the last thing you want to do is disturb the other members of your household to clean your teeth. Unfortunately, full-size picks and flossers can often be heard beyond multiple closed doors. I think we can all agree that a jackhammer-like sound to clean our teeth and gums is unnecessary at midnight.

Quietest Water Flosser Reviews

These are currently the top models in the quiet department. We made sure to include a mix of budget and premium models. In general, you’ll find that Waterpik offers the highest quality and most reliable models with the most trustworthy warranty.

Also, Waterpik is the only brand in the guide backed by authentic ADA acceptance. For these reasons, Waterpik models do cost more than the budget alternatives in this guide. Below, we share our reviews of each model, the highlights, and things to be aware of before you make your final decision.

1. Akunbem Professional Cordless Water Flosser

Our top budget pick for the quietest water flosser is this unit by Akunbem. The main feature that sets this model apart from others on the market is a DIY mode. This “do-it-yourself” mode gives you full control over water pressure, which we think is pretty nifty.

To operate DIY mode, simply select DIY mode, then long-press the power button until you land on your desired pressure. Clearly, there’s a bit of a learning curve, but once you figure it out, it’s a really nice feature to have.

In case you don’t want to use DIY mode, the Akunbem pick also features Soft, Normal, and Pulse modes. Next, the battery life of this unit is impressive, to say the least. According to Akunbem, its 2000mAh rechargeable lithium battery provides up to 30 to 40 days of continuous daily use per charge. Considering we’ve seen flossers that run through a charge in a single session, 30 to 40 days is quite remarkable.

Another feature we really like in most good budget water flossers is USB compatibility. With this unit, you have the option to charge the unit by connecting it to your computer, a wall outlet, or a power bank. Compared to units that require a wall outlet and use a proprietary power adapter, Akunbem’s USB power is more convenient for travel and everyday use.

2. Waterpik Sidekick Portable Water Flosser

If you want a quiet Waterpik, the Sidekick portable flosser is your best option. This compact model is an excellent choice for people with little counter space and for travel. The design saves space by storing the motor and flosser inside the reservoir when not in use. Compared to budget models that often include cheap cloth travel bags, the Sidekick comes with a nice branded Waterpik zip bag.

Unlike other Waterpik models, the Sidekick features an all-in-one stylus. The design is great since it’s compact, however, there’s no option to use standard Waterpik attachments. The good news is replacement stylus attachments for the Sidekick are easy to pick up and affordable.

Another feature you’ll like is the large reservoir size for a unit so compact. Of the five models in this guide, the Sidekick has the largest reservoir and cleaning time per fill. A full minute of cleaning per fill is enough to get the job done in most cases, whereas the other units you’ll most likely need to refill once or twice. Lastly, Waterpik offers the most trustworthy warranty in this guide and the longest at 3 years for its Sidekick model.

3. Zerhunt Cordless Water Flosser

The second budget model in our top 5 is this cordless one by Zerhunt. Currently, it’s one of the best-rated cordless water picks available. We noticed that several companies sell this type of water flosser, and it’s one of the quietest models.

One discrepancy we want to point out is the stated cleaning time per fill. According to Zerhunt, its flosser provides 75 seconds of use per fill. In reality, expect anywhere from 45 to 60 seconds, which is about par for the course. The IPX7-rated body of the Zerhunt flosser is safe to use in the shower.

The package includes a total of six color-coded 360º rotating nozzles with several varieties to take care of different dental needs. Battery power is good with this model at up to two weeks of continuous daily use per charge and 4-hour charging time. We also like that this model uses USB power rather than relying on a wall outlet.

4. Liberex Cordless Water Flosser with OLED Display

The Liberex pick is one of our favorites and the best cordless water flosser for braces of the models in this guide. The reason it’s good for braces is the included orthodontic attachment that’s specifically designed to clean braces. Another clear advantage is the easy-to-read OLED display. Compared to an LED indicator, it’s a lot easier to see your current setting and the battery life on this unit’s OLED display.

In total, there are 3 pressure settings and a pulse setting. Choose between soft, medium, and power cleaning from 40 to 120 psi. Next, we really like the shape of this model, and we think you’ll find it more comfortable to hold than other competing budget models.

Similar to most other budget models, the Liberex flosser features convenient USB charging, up to 14 days of continuous daily use, and 4-hour charging. Additionally, the IPX7 waterproof design makes this flosser safe to use in the shower. One final feature we want to highlight is the button at the top of the unit for rotating and locking the attachment in place.

5. Waterpik Cordless Advanced Water Flosser

The second quietest Waterpik model is the Cordless Advanced. Of the cordless models in this guide, this unit is the most premium and delivers the most thorough cleaning experience. You’ll also find that Waterpik models are more ergonomic and easier to maneuver inside your mouth in most cases.

One key difference between this model and the Sidekick model – other than this unit being cordless – is the attachments. The Waterpik Advanced accepts standard Waterpik attachments, while the Sidekick model uses the specialty stylus attachment only. With the advanced model, you have the option to use Waterpik’s Plaque Seeker Tip (PS-100E), Orthodontic Tip (OD-100E), and others.

The package even includes 1 orthodontic tip and 1 Plaque Seeker tip, so if you or someone in your family has braces or dental work, this is one of the better quiet models on the market. A couple of drawbacks to keep in mind are the 3 total pressure settings, and this unit must be plugged into a wall outlet (no USB charging), though it is 100 – 240 VAC for safe global use.

Bottom Line

When choosing the quietest water flosser, it’s best to stick with cordless and portable models. In our experience, full-size corded models are always noisier. Also, it depends on how sensitive you and the members of your household are to noise. Some people find that standard models aren’t very loud, while the sound is irritating to others.

In conclusion, choose a Waterpik model if you want the most reliable flosser that does the best job. If you’re okay with a budget alternative, most budget models cost about half as much as a Waterpik. In our experience, they do work well, and there’s more than enough positive feedback to back up their effectiveness.

Problems only come into play if the flosser happens to break or if you’re used to using a Waterpik. If this is your first water flosser, a budget model is more likely to be okay since you won’t compare it to your previous Waterpik.
